Every appointment-based business has the same problem — and nobody's solving it at the source.

Here's what we kept hearing.

A salon owner in Austin told us she knew half her clients weren't coming back — she just couldn't see which half. A medspa owner said the same thing, in different words: "I can't tell you which of my clients stopped booking." A dental practice said they had 400 patients overdue for hygiene recall and no systematic way to bring them back.

Then a mortgage loan officer — a personal friend — said something that reframed the whole thing for us: "My best deals are already in my database. I just can't see them."

The software problem, not the marketing problem.

Every practice we talked to was already spending money on marketing. They had a booking system, a CRM, maybe a reputation tool, maybe a Zapier workflow that kind of half-worked. What they didn't have was a single place that looked at their past-client book and told them who to reach out to today, why, and what to say.

That's what TechStack is. Three engines — Retention IQ for service businesses losing clients to silence, Revenue IQ for scheduling that leaves money on the table, and Refi IQ for mortgage officers working a career book. All three read the data that's already in your system and translate it into specific actions.

One rule we never break.

We don't send messages on your behalf. Every piece of outreach drafts in the app for your review. You read it, adjust it to sound like you, and send it from your own system. We show the numbers; you keep the relationship. That's the deal.
